CHARLES OHAMBERLIN, OF LOWELL, MASSACHUSETTS.

SPECIFICATION forming part of Letters Patent No. 259,366, dated June 13, 1882.

Application filed February 17, 1881. (No model.)

To all whom it may concern Be it known that 1, CHARLES CHAMBER- LIN, of Lowell, in the county of Middlesex and Commonwealth ofMassachusetts, have invented certain new and useful Improvements in Spindle-Protectors for Carriage-Axles, of which the following is a specification.

My invention is in some respects similar to the invention described in Letters Patent No. 231,691, granted August 31, 1880, to John A. Tillinghast; and it consists in a protector provided with a downwardly-enlarged drip-receiver; also, in a protector provided with a downwardly-enlarged drip-receiver and a hole; also, in a protector provided with a downwardly-enlarged drip-receiver and a hole, in combination with a plug; also, in aring closely fitting over the axle-box and provided at its inner end with an internal annular flange, in combination with said axle-box; also, in a ring closely fitting over the axle-box and provided at its inner end with an internal annular flange and an external annular flange, in combination with said axle-box and a protector provided with a downwardly-enlarged drip-receiver; also, in a ring provided at its inner end with an external annular flange, in combination with a protector having a downwardly-enlarged drip-receiver, all as and for the purpose hereinafter specified.

In the accompanying drawings, Figure l is a side view of a part of the axle, the protector, and the hub. Fig. .Zis a side view of the axle and a vertical longitudinal section of the hub, axle-box, protector, and nut. Fig. 3 is an elevation of the end of the protector nearest the hub. Fig. 4 is a vertical longitudinal section of the protector.

A is the axle; B, the spindle, provided with the collar 0; l), the hub, and E the axle-box, all of the usual construction, except that the hub is provided withannular grooves to receive the flanges of the protector and nut. At the outer end of the spindle B is a nut, F, which serves the usual purpose of holding the wheel on the spindle, and which also keeps the oil from running out of the axle-box and the dust from getting into the axle-box, said nutbein g provided not only with the usual circular flan ge,G,but also with acylindrical flange, G, which projects from the circumference of the flange G and-enters an annular groove, H, in the outer end of the hub D, thus completely covering and closing the outer end of the axle-box. At the other end-of thehub, and surrounding the axle, is the protector I 1, provided with a rectangular hole, J, to admit the axle, and a cylindrical flange, K, which enters an annular groove, K, in the inner end of the hub and prevents the entrance of dirt and sand into the inner end of the axle-box E. In these respects my protector is like the one described in the patent above referred to. I also divide the protector horizontally into two segments, but make the upper part or segment, I, smaller than the lower, 1, dividing said protector near the top of the axle, so that a part of the hole J is in each segment II. I secure the segments together by screws L L, instead of by bolts cast upon the lower segment. I think this construction is better where the protector needs to be fitted to the axle. Now, the inner end oft-he axle-boxis flush with the inner end of thehub, as usual; but I drive a metallic ring, M, over the inner end of the axle-boxinto the wood of the hub. This ring M fits the axle-box closely, and is provided at its inner end with an internal annular flange, N, which flange, with the end of the axle-box, froms an internal annular chamber, 0, in said ring (the chamber may be formed wholly in the ring) to receive a surplus of oil from the axle-box and to prevent said oil from coming in contact with the wood of the hub. Thus I accomplish two very desirable objectsone being that the oil-chamber 0 makes it unnecessary to oil the wheels more than onefourth as often, and the other object being the prevention of the deleterious action of the oilupon the wood of the hub, this action being to soften the wood and thereby to loosen the axle-box. As will be seen, the outer diameter of the ring is great est at its inner end, so that a surplus of oil running out of the chamber 0 will not follow the ring up to the hub, but will drop from the lowest part of the ring when the wheel is not in motion, or will be thrown by centrifugal force from the greatest external diameter of the ring whenthewheelisinmotion. 'Iheinnerendofthe ring M, with its enlarged outer diameter, above described, reaches back about to the middle of the protector I 1. Now, the protector is enlarged downward at the bottom, between the flange K and its inner end or face, to form an oil-receptacle, P, to receive the drip or overflow of oil from the chamber 0 and to hold the oil away from the wood of the hub. The oil may be removed from the protector by removing the screw-plug Q, or the plug Q may be dispensed with, leaving the hole R open at all times for the oil to run out. rangeinent there is no danger of getting sand into the axle-box by the splashing of dirt and mud in wet weather, inasmuch as any dirt or water which gets into the sand-box or protector will be prevented by the ring M from entering the axle-box, and may be removed through the hole R, or will run out if the hole he left open. In washing carriages with a hose it will be best to leave plug Q out, and the water will then run out of the protector as fast as poured in, without entering the axle-box.

New axle-boxes may be formed in one piece with the ring M.

I claim as my invention- 1. The protector I I, provided with a downwardly-enlarged drip-receiver, P, as and for the purpose specified.

2. The protector I I, provided with a down- WVith this ar-- wardly-enlargcd drip-receiver, P, and a hole, R, as and forthe purpose specified.

3. The protector I I, provided with a downwardly-enlarged drip-receiver, P, and a hole, R, in combination with the plug Q, as and for the purpose specified.

4. The ring M, closely fitting over the axlebox IE, and provided at its inner end with an internal annular flange, N, in combination with said axle-box, as and for the purpose specified.

5. The ring M, closely fitting over the axlebox E, and provided at its inner end with an internal annular flange, N, and an external annular flange, in combination with said axlebox and a protector, I 1, provided with a downwardly-enlarged drip-receiver, P, as and for the purpose specified.

6. The ring M, provided at itsinner end with an external annular flange, in combination with a protector, I I, having a downwardlyenlarged drip-receiver, P, as and for the purpose specified.
